与智能合约互动以获取令牌ID

Question

我的平台上有一个功能，可以发现用户是否是特定令牌的持有人，

const [tokenId, setTokenId] = useState(false);

const checkOwners = async () => {
    if (ethereum) {      
      const provider = new ethers.providers.Web3Provider(ethereum);
      const signer = provider.getSigner();
      const nftContract = new ethers.Contract(contractAddress, abi, signer);      
      if (currentAccount !== null && nftContract !== null) {
        let walletOfowners = await nftContract.tokensOfOwner(currentAccount);
        if (walletOfowners.length > 0) {
          setTokenId(true);
        } else {
          setTokenId(false);
        }
      }
    }
};

但我希望我的代码获得连接用户所拥有的令牌（IDS）。智能合约确实具有tokensofowner功能。

 //Returns all IDs owned by a particular holder.
    function tokensOfOwner(address _owner) external view returns (uint[] memory) {

        uint tokenCount = balanceOf(_owner);
        uint[] memory tokensId = new uint256[](tokenCount);

        for (uint i = 0; i < tokenCount; i++) {
            tokensId[i] = tokenOfOwnerByIndex(_owner, i);
        }
        return tokensId;
    }
    ```

我发现了我需要的功能：

  const tokensIdsOfOwner = async () => {
    if (ethereum) {
       const provider = new ethers.providers.Web3Provider(ethereum);
       const signer = provider.getSigner();
       const nftContract = new ethers.Contract(contractAddress, abi, signer);        
         if (currentAccount !== null && nftContract !== null) {            
           let ownerTokenId = await nftContract.tokensOfOwner(currentAccount);            
           console.log(ownerTokenId.toString());
           setOwnerIds(ownerTokenId.toString());
         }
    }
  };
